Delivery data and AI chat

Per-product delivery information uses custom.lead_time_days for production lead time and custom.shipping_class for shipping class. Ordinary theme use does not require entering another namespace.

Only for products that need this information, create the definitions, enter product values, then verify the Delivery promise badge. The theme does not invent a lead time for products with unknown delivery data.

Configure chat connections and answer behavior in the app. Sharing a metafield location alone does not make holiday, cut-off and transit calculations identical. Automatic synchronization of theme settings into the app is not implemented. Check the same product’s storefront display and AI answer before publishing.

For stores with older mappings, back up the original values and verify the display after migration. Original data is not automatically deleted.
